Description
Technical field
This utility model belongs to textile chemical fiber equipment technical field, is specifically related to the Extraction For Pa 6 Chips conveyer device of the anti-gasification of a kind of automatic constant-temperature.
Background technology
Nylon-6 section have to pass through 102 DEG C～120 DEG C extraction water extract qualified after, just can spin and cause fiber.In stagewise extraction process, section, after one-section abstraction completes, is transported to two-stage extraction tower by rotary valve, slices synthesis method pump, conveyance conduit, extraction water separator；The section of two-stage extraction tower picks three sections of extraction towers through rotary valve, slices synthesis method pump, conveyance conduit, extraction water separator.
In extraction tower, section and extraction water temperature are high, and the beneath material of tower is unstable and pressure oscillation is big, causes that extraction water is vaporized into water vapour in conveyance conduit, and rapid spatial expansion produces air-resistance phenomenon.In this condition, slices synthesis method pump can serious putty, the normal conveying of impact.So will result in the material level of leading portion extraction tower higher, and back segment extraction tower material level reduces, extraction process cannot be stablized, and also can cause the risk dropping product or stopping production, and has had a strong impact on the quality of section.
Summary of the invention
Technical problem to be solved in the utility model is in that to provide the Extraction For Pa 6 Chips conveyer device of the anti-gasification of a kind of automatic constant-temperature, solves the problem that extraction water easily gasifies, it is prevented that the generation of air-resistance phenomenon, it is prevented that slices synthesis method blocks.
This utility model is achieved in that
The Extraction For Pa 6 Chips conveyer device of the anti-gasification of a kind of automatic constant-temperature, including one-section abstraction tower, two-stage extraction tower, three sections of extraction towers, passes sequentially through extraction conveyance conduit and is connected；The extracting vertically conveyance conduit between extracting vertically conveyance conduit and described two-stage extraction tower and described three sections of extraction towers between described one-section abstraction tower and described two-stage extraction tower is separately installed with a cooling passageway pipe, the upper end of each cooling passageway pipe described is provided with cooling water inlet pipe, and the lower end of each cooling passageway pipe described is provided with cooling water outlet pipe；Described cooling water inlet pipe is provided with a stop valve, and described cooling water outlet pipe is provided with a Pneumatic valve and a temperature sensor, described Pneumatic valve and described temperature sensor and is connected respectively to workshop DCS control system.
Further, described cooling water inlet pipe is additionally provided with a Pressure gauge.
Further, the length 4～5m of described cooling passageway pipe, diameter is 1.5～2 times of described extraction pipe diameter.
Further, the specification of described stop valve is DN25, PN16.
Further, the specification of described Pneumatic valve is DN25, PN16.
Further, described cooling water outlet pipe is additionally provided with a drain valve.
The utility model has the advantage of: cooling jacket pipe allows the high-temperature extraction water extracted in conveyance conduit effectively lower the temperature and to keep constant temperature (extraction water temperature control is at 80 DEG C～90 DEG C), make its no longer generating gasification, to prevent from managing the generation of interior air-resistance phenomenon, it is prevented that slices synthesis method blocks；The instability and the polymerization that avoid section extraction process are dropped product, are stopped production, thus stabilizing technological process, reducing production loss, improve product (section) quality.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As it is shown in figure 1, the Extraction For Pa 6 Chips conveyer device of the anti-gasification of a kind of automatic constant-temperature, including one-section abstraction tower 1,2, three sections of extraction towers 3 of two-stage extraction tower, pass sequentially through extraction conveyance conduit and be connected；The extracting vertically conveyance conduit between extracting vertically conveyance conduit and described two-stage extraction tower 2 and described three sections of extraction towers 3 between described one-section abstraction tower 1 and described two-stage extraction tower 2 is separately installed with a cooling passageway pipe 4,5, the upper end of each cooling passageway pipe 4,5 described is provided with cooling water inlet pipe 6,16, and the lower end of each cooling passageway pipe 4,5 described is provided with cooling water outlet pipe 7,17；Described cooling water inlet pipe 6,16 is respectively equipped with the stop valve 8,18 that a specification is DN25, PN16, described cooling water outlet pipe 7,17 is respectively equipped with Pneumatic valve 9, the 19 and Pt100 temperature sensor 11,21 that a specification is DN25, PN16, and described Pneumatic valve 9,19 and described temperature sensor 11,21 are connected respectively to workshop DCS and control system.Pt100 temperature sensor 11,21, to carry out signal respectively chain with Pneumatic valve 9,19, and this signal is connected with the workshop DCS computer controlling system, so as to the aperture of autocontrol valve 9,19 can be carried out according to coolant water temperature, thus reaching thermostatic control voluntarily (being controlled by outlet coolant water temperature at 35 DEG C～45 DEG C), it is beneficial to extract the extraction water thermostatic (by extraction water temperature control at 80 DEG C～90 DEG C) in conveying pipe.
